Which Soap Claims Turn a Bar Into a Notifiable Cosmetic

A soapmaker once showed me two bars, chemically almost identical, same base recipe, same batch even. One label said "gentle cleansing bar." The other said "moisturizing bar that softens skin." Only one of those two bars needed a CNF. Same soap. Different words. Different regulatory category entirely.

The line between true soap and cosmetic

Health Canada treats "true soap," meaning alkali salts of fatty acids sold with only a cleansing claim, differently from a cosmetic. That exemption is narrow and it's about the claim, not the ingredients or the process. The moment your label or marketing says the bar does something beyond cleaning, moisturizes, treats a skin condition, softens, it steps into cosmetic territory and needs a Cosmetic Notification Form.

This surprises a lot of small soap businesses because it feels backwards. You'd think the thing that matters is what's actually in the bar. But regulatorily, the claim is what defines the category here. Two bars with identical formulas can sit on opposite sides of the notification requirement purely based on the words printed on the label.

Phrases that push a bar into cosmetic territory

Here's a rough catalog of the kind of language that typically crosses the line from a cleansing claim into a cosmetic claim:

• "Moisturizing" or "hydrating"
• "Softens skin" or "leaves skin soft and smooth"
• "Anti-acne" or "clears blemishes"
• "Reduces the appearance of" anything, wrinkles, redness, pores
• "Nourishes" or "repairs" skin
• "Anti-aging"
• "Soothes eczema" or references to any specific skin condition
• "Exfoliating" claims tied to a cosmetic benefit rather than pure mechanical cleansing

Compare that against language that tends to stay within the cleansing-only lane:

• "Cleanses" or "washes away dirt and oil"
• "Gentle bar soap"
• "For hands and body"

The safest phrases describe what the bar removes, not what it adds to or changes about the skin.

Why this catches handmade soapmakers specifically

Handmade soap marketing leans heavily on sensory, benefit-driven language because that's what sells. "Made with shea butter to soften and nourish" sounds lovely and it's honest about what shea butter can do. But that same honesty is exactly what makes it a cosmetic claim rather than a cleansing claim. The ingredient itself isn't the problem. The promise attached to it is.

This is also where cold process soapmakers sometimes get confused about their own products. A bar can be 100% true soap by chemistry, saponified oils and nothing else, and still require a CNF the instant the label promises a cosmetic benefit. Conversely, a bar with added cosmetic ingredients like a superfatting oil or a botanical extract can still avoid notification if the marketing sticks strictly to cleansing language, though at that point you're leaving a lot of your product's actual selling points off the label.

What filing means in practice

If your soap does need a CNF because of its claims, the process is the same as any other cosmetic notification, filed through the Cosmetic Notification System within 10 days of first sale, ingredients listed by INCI name with concentration, and you'll receive a CN number once it's processed. It's a notification rather than a pre-market approval, so it doesn't slow your launch the way an approval process would, but it's still a real regulatory obligation with a real deadline.

Deciding which path fits your business

If you genuinely only want to sell cleansing bars and you're comfortable keeping your marketing disciplined around that, staying in the true soap lane avoids the notification requirement entirely. But if your brand depends on describing what your butters and oils actually do for skin, and most successful soap brands do lean into that, you should plan for your products to be cosmetics from day one rather than trying to walk a claim right up to the line.

Either way, it's worth deciding this deliberately for each product rather than discovering after the fact that a label reviewer or a customer complaint flagged a moisturizing claim you didn't think twice about. If you land on the cosmetic side, Cosmetic Comply can take your ingredient list and file the CNF for you, mapping every ingredient to its INCI name and CAS number and returning a trackable CN number, so the claim you actually want to make doesn't get held up by the filing side of things.
